Talk:Malleability

From Wikipedia, the free encyclopedia

August 2007

My argument concerns the difference between Malleability and Ductility. Firstly, I concur with the assertion that both are mechanical properties since both describe the response of a material to applied load. However, the distinction between the two is that malleability refers to the maximum plastic deformation possible under compressive load whereas ductility is the maximum plastic deformation possible under tensile load. So materials that are extruded need to be malleable and materials that are drawn must be ductile.

Shouldn't we get rid of the "root word" and "part of speech" thing? This is an encyclopedia article, not a dictionary entry. -- Ben

What is the scientifc word for hardness? It's along the lines of malleability, but the antonym.- John

May I inquire to any quantitive measuring systems for malleability?

[edit] Physical vs. Mechanical Properties

Malleability and ductility are mechanical properties of materials, not physical properties. Mechanical properties are responses to applied loads. Therefore, the current entry for malleability contradicts the entry for physical properties.

[edit] CU Material Science Class?

According to our dissections in class and with many professors and experts, a mechanical property is the reaction of a substance when a load is applied, which is not necessary for measuring malleability. Therefore, malleability must be a physical property or possibly neither. Anyone have anything to say on the possibility of it being neither? Thatcherk 03:15, 11 July 2007 (UTC)

[edit] Merging articles

Since the properties are so closely related, this proposal seems sensible to me. At the same time, the text can be edited and rationalised. Peterlewis (talk) 17:08, 17 May 2008 (UTC)
